With a very high probability, Recovery Toolbox for Outlook can restore an array of data from .pst files to their original state before they were damaged. To test this statement, it is necessary to:

Download, install, and run the DEMO version of Recovery Toolbox for Outlook.

Select a damaged .pst file.

Run the analysis of the damaged PST file.

Review the contents of the .pst file on the preview page.

How to Fix Outlook

If you need to fix an Outlook file that is corrupted for any reason, then the full version of Recovery Toolbox for Outlook will allow you to do this in a few simple steps. Outlook PST file repair occurs by copying the corrected data from the damaged .pst file to a new PST file on disk. The tool doesn’t fix or modify the existing PST file. All recovered data transfers to a new PST file with preservation of the folder structure and properties of all objects.

Our engineers have analyzed the content of OST (source) and PST (destination) files. The analysis revealed the types of data that are not carried over to the PST file after OST file conversion:

old versions of messages, contacts, files and other objects

removed objects

blocks of data from earlier versions of messages, contacts, files and other objects. It is impossible to use these blocks to fully recreate the original object, which is why they can be treated as junk.

In other words, when you remove or modify a message, contact, reminder or meeting, the object is only marked as removed, but is not removed physically and remains in the OST file. The new version of the object is written to a newly allocated space, but the old version remains in the OST file as well.

If Outlook is in active use, the size of the OST file can grow quite significantly, while the actual size of data in the file remains the same.

In order to optimize disk space consumption and remove old elements, you need to configure the AutoArchive feature in Microsoft Outlook.

Note: it is recommended to backtrack the changed options after the export of the recovered data in Microsoft Excel has been completed.

search for and reading of old versions of documents is used by attackers for stealing users’ confidential information;

search for and reading of deleted and old versions of documents is used by police authorities to collect compromising information (Forensic Mode);

Recovery Toolbox for Outlook enables the user to search for data deleted from an OST/PST file and save it to the disk.

When converting large OST files (4 GB and above), you will have to use a 64-bit computer system. All program components required for converting OST to PST must be 64-bit. These include:

Microsoft Outlook 64-bit

Microsoft Windows 64-bit

Recovery Toolbox for Outlook versions 4.0 and above

This allows you to bypass the limitations on the RAM that can be used by each component and convert OST files of virtually any size.

Converting huge OST files to PST files

Once all necessary components have been installed, run Recovery Toolbox for Outlook and perform the following actions:

choose the OST file you need to convert on the program's first screen

choose Convert on next page of Conversion Wizard

choose the emails, contacts, and other information you want to transfer from the OST to the PST file

choose the option to save as a PST file

type or select a folder to use to save the data on the disk

The process of reading the OST file and then exporting it to PST takes a significant amount of time. The time it takes to convert OST to PST depends on your computer's performance, particularly the speed of your disk subsystem.

To recover a very large Microsoft Outlook PST file (more than 4 GB), you'll need to have Recovery Toolbox for Outlook installed on your computer, as well as the following:

Microsoft Outlook 64-bit

Microsoft Windows 64-bit

If this software is installed, Recovery Toolbox for Outlook won't be limited to the size of operating data that 32-bit systems have. The program will be able to completely restore and save the data in a new PST file when working with the 64-bit versions of Microsoft Outlook and Microsoft Windows. If Microsoft Outlook 32-bit is installed on the computer, Recovery Toolbox for Outlook will encounter a limitation due to the amount of RAM that can be used in the restoration of data.

If you have the installation disc or distribution kit, you can install Microsoft Outlook 64-bit along with the 32-bit version of Microsoft Outlook. You'll find instructions for the installation of Microsoft Outlook 64-bit here.

You should now see the System Properties Window. Please select Advanced tab. You should see three sections. The top section is labeled Performance and has a Settings button. Click this button.

Select the Data Execution Prevention tab.

Select the option which reads Turn on DEP for all programs and services except those I select.

Try to recover your data to separate files, it may help. Make sure you have enough free space on your storage drive to save recovered data. Do not try to save the file with results under the same name as that of the damaged file.

You should send the log file of the program to our support service. The log file is located in the same folder where Recovery Toolbox for Oulook is installed (for example, D:\Program Files\Recovery Toolbox for Outlook\Err.log).

Also, let us know the version of your OS (Operating System) and Outlook.

Disable your antivirus, it can block access to the Outlook data for our program.

Don't run the Outlook during and before recovery. If you choose to save data to new PST files, Outlook will start in hidden mode automatically.

Try to make the recovery to separate files, not to PST.

If you have another computer, please try to recover this file on it.

Send to our technical support your original file for a recovery if my suggestions can't help.

You can create multi-volume archive from the orignal OST/PST file using WinRar program (https://rarlab.com). It is free trial. The size of each volume must be ~30-50Mb. And upload all files on www.dropbox.com service and send us the links to the all files.

when Microsoft Outlook tries to open several Personal Store Folders that use one PST file

or if the Personal Store Folder is registered in Microsoft Outlook, but the original PST file does not exist on the disk or if the path to it is incorrect

To solve the problem, you should:

Close Recovery Toolbox for Outlook and Microsoft Outlook

Restart the computer

Start Microsoft Outlook. Ignore the message This Personal Folders file (pst) is already in use with this profile while restarting Microsoft Outlook.

Close all PST files Personal Store Folders being used, except for the main Personal Store Folder in the left panel of Microsoft Outlook. To do it, you should right-click the Personal Store Folder item and select the Close Personal Store Folder item in the context menu.

Close Microsoft Outlook

Open Microsoft Outlook again. If the error message This Personal Folders file (pst) is already in use with this profile appears again, the path to the main Personal Store Folder is incorrect or the PST does not exist on the disk. To fix this error, you should:

Find the source PST files on the disk. The best way to do it is to use the Microsoft Windows search feature (click Start | Search | For Files and Folders...), select All files and folders (for Windows XP) and then search for *.pst files on the computer.

Set the correct path to the file and its name in the properties of the main Personal Store Folder (right-click the Personal Store Folder item and select the Properties item in the context menu).

Microsoft Outlook data files contain main objects ( messages, contacts, notes, reminders, attached files and others) and service objects that are not shown to the user. While writing the recovered data to the new .pst file, the program does not write some service objects because there is no need to do it.

You performed the recovery operation at another computer or where another version of Outlook is installed. Our software uses Outlook components to compile the structure of a new PST file(s). So the recovered PST file is compatible with the version of Outlook that is installed on the system where the PST file was recovered.

Cases differ. Our software requires that the damaged file is fully readable so if you can copy the file to a normal, not crashed hard drive, our software will probably help you. Please download our software and try it for free. If it can help in your case, you can purchase it to disable the trial limitations.

Every object saved by Outlook to a file is stored in several blocks of up to 512 bytes. When a message is deleted, these blocks are not deleted and remain in the file. However, when new emails are sent or received, these blocks may be overwritten. As a result, the deleted email can be recovered only partially, for example:

if there is a subject, the message body or attachments may be lost;

if the subject is lost but the body is there, the email will be restored without From and To fields;

if the message subject and body have been overwritten, the attachment will be saved as a standalone file;

and so forth.

Recovery Toolbox for Outlook does everything possible to recover deleted data. If an object's data blocks are overwritten by Outlook, the object will be recovered only partially.

Repairing mailboxes after the corruption of the Exchange Server database file.

If the Exchange Server database file gets damaged, the server will still have *.edb files with users' emails. There will also be .ost files on users' computers containing the personal data of each user.

OST files can be quickly and easily converted to PST files using Recovery Toolbox for Outlook.

You can try recovering .edb files using Recovery Toolbox for Exchange Server. This tool converts individual mailboxes to .pst files.

We recommend trying both recovery methods to recover as much data as possible.

This OST-to-PST converter is an easy-to-use tool that operates like a wizard. With it, you can convert an .ost file to the .pst file format in a few simple steps. No special know-how is needed in order to use the Recovery Toolbox for Outlook OST-to-PST converter.

Microsoft doesn't currently offer a special Outlook OST-to-PST converter. All OST2PST converters have been designed by ISVs. Recovery Toolbox for Outlook, however, has a demo mode that lets you convert five objects per folder.

Recovery Toolbox for Outlook can read *.ost files any versions of Microsoft Exchange Server, any version of Microsoft Outlook (32- or 64-bit, ANSI or UNICODE). Software can read and convert *.ost files with any size of file.

The size of the converted .pst file shows the actual size of information stored in the ost file. If you do not make archives and do not start Cleanup Tool regularly for the original Offline Storage Folders, then the .ost file size is only growing. As a result, only 5-10% of the file can be used for a real user's data.

For the use of OST-to-PST conversion on a computer running Microsoft Outlook, the .pst file version will be the same as that installed in Microsoft Outlook. If the computer has Microsoft Outlook 2007 or higher installed, the size of the resulting .pst file can exceed 2Gb. If you use MS Outlook 98-2003, the size of the resulting file will be limited to 2Gb. In this case, Recovery Toolbox for Outlook will create several .pst files in which to store all the data from the source .ost file.

Recovery Toolbox for Outlook exports messages, contacts, appointments and other data from *.ost files as MSG files. The software converts and saves all data from .ost files to the .msg file format. Later, the user can drag and drop or import the saved *.msg files in any of the popular client software programs, including Lotus Notes, Microsoft Live, The Bat, Eudora, Incredimail, Mozilla Thunderbird, etc.

Microsoft Outlook has no function with which to import data from *.ost files. To open an *.ost file in Outlook, the Exchange Server and Windows Domain Controller must be working and available for user authentication in both of the respective services. Only after that is it possible to transfer the contents of an .ost file that is open in Outlook to a .pst file that is also open in Outlook.

If the Exchange Server or Windows Domain Controller isn't accessible or doesn't work, or if the user can't be authenticated, access to the data will be denied and Outlook won't open the .ost file.

The original .ost file must be converted to a pst file using Recovery Toolbox for Outlook and then opened in Outlook. Conversion from OST to PST using Recovery Toolbox for Outlook doesn't require the availability of Exchange Server or Windows Domain Controller.
